MOVABLE HOOD FOR STOVES OR RANGES.

SPECIFICATION forming part of Letters Patent No. 503,343, dated August15, 1893.

Application filed January 24, 1893. Serial No. 459,577. (No model.)

To all whom it may concern.

Be it known that I, BENJAMIN F. CARPEN- TER, a citizen of the UnitedStates, residing at Roselle, Union county, New Jersey, have inventedcertain new and useful Improvements in Movable Hoods for Stoves andRanges, fully described and represented in the following specificationand the accompanying drawings, forming a part of the same.

The object of this invention is to furnish a means of eifectuallywithdrawing thesmoke, odors, vapor and heated air which rise from acooking apparatus, and also to protect the cook from the greater part ofthe heat which is radiated therefrom; and reduce the temperature of thekitchen and other rooms when desired. Also to facilitate cookingoperations, heating irons, baking, &c., by confining the heat for thevarious operations to the stove instead of allowing it to escape byradiation. Also to economize fuel by such improved application of theheat, also for confining the heat and conducting it to other rooms ifdesired.

25 My improvements are applicable to any cooking apparatus, Whether itconsists in a brick set range which is fitted partly into a recess in achimney breast, a detached range which is set adjacent to the chimneybreast, or a stove which is set some distance from the chimney breastinto the apartment.

For convenience, I have used the term range herein to include all formsof cooking apparatus.

My invention consists in the particular means hereinafter set forth, bywhich a counterbalanced hood is applied to inclose the top of the stove,and is furnished with an extensible connection to the ventilating flue.By such extensible connection the hood may be drawn downward to coverthe cooking utensils and prevent the radiation of heat into the kitchenduring the operation of cooking; and the hood is also fitted movably toguides and connterbalanced,so that it maybe raised when access isrequired to the utensils, or the top of the range. The extensibleconnection consists in a movable curtain attached at the top to a springroller, and at its bottom end to the edge of the hood. The guidesprovided at the edges of the hood form, with the ourtain and the hood, apassage extending from the bottom of the hood upward to the ventilatingflue, which flue is thus in constant connection with the hood. lheguides furnish the sides of such passage, while the curtain furnishesthe front of the same, and the rear of the passage is closed in anysuitable manner, depending upon thelocation of the range. Where therange is brick set, the brick wall of the chimney breast furnishes theback of the passage, but where the range is detached, a supplementalwall of wood or metal may be supported upon the range to form the rearwall of the passage; the guides in either case being affixed to thefront of the wall, to form the sides of the ventilating passage.Aventilating flue is connected with the passage which lies between therear Wall and the curtain, and the curtain thus forms an extensible oconnection between the hood and the flue.

The invention will be understood byreference to the annexed drawings, inwhich- Figure 1 is a front elevation of a brick set range with myimprovements applied thereto. 7 5 Fig. 2 is a front elevation of adetached range with the same improvements. Fig. 3 is an edge view of theparts shown in Fig. 2. Fig.

4 is a sectional elevation of the hood with the rear wall, and guidesfor supporting the same. Fig. 5 is a plan of the fixtures with the topcovering removed, and the guides in section on line at, m, in Fig. 6,the framek' of the hood being also added to the figure. Fig.6 is a frontelevation of the top of the fixtures with the curtain and curtainfixtures broken away at the end; and Fig. 7 is an end view of thecurtain roll and curtain.

In the brick set range shown in Fig. 1, the range top A is shown; withhot closets B supo ported above the same. i

O designates the chimney breast or brick setting of the range, whichforms the rear wall of the ventilating passage 1; and the guides t areaffixed to the front of such wall. 5

In Figs. 2, 3 and 4, the supplemental wall is supported upon a detachedrange, and the guides are in like manner attached to the front of thesame. The supplemental wall lettered I in Figs. 3 and 4., is shown ofsuhicient roo thickness to be formed of wood, and may be fire-proofed ashereinafter set forth; but as such part of the structure serves merelyas the rear wall of the passage, it may be made of sheet metal or anysuitable material. The remaining parts of the construction would be thesame, whether applied to a range set in brick work, or to a detachedrange, the guides being surmounted by a top P adapted to close thepassage Iat the upper end,and the outer sides of the guides beingprovided with ver: tical pockets n to receive weights for balancing thehood.

Acasing Z is shown beneath the front of the top P, to close part of thepassage, and to incase a spring roller 1' to which the curtain 9 wouldbe attached. The curtain is shown, provided at the bottom end withabarfwhich is shown connected detaohably to the top of the hood D byhooks h. hood is formed with a vertical plate to form an apertureadapted to furnish access to the top of the range; for broiling, orother culinary operations, and for heating irons for laundry purposes. Asliding door 10 1s fitted to such vertical plate to close the aperturewhen desired. A handle 11 is affixed to the front of the vertical plateto raise and lower curtain barf to detach the curtain from the hood andto raise and lower thecurtain independently. Ohainsj are shown attachedto the barfand to the top of the hood to limit the separation of thesame.

The hood is shown elevated in Fig. 1, with the curtain. attachedthereto, exposing the entire top of the range as well as the ovens orliotclosets B; but the hood is shown drawn downward in. Fig. 2, withthebottom frame of the hood inclosing the top of'the range.

The means for disengaging the curtain from the hood is shown in Fig. 4,where the top of the hood is shown furnished with a downwardly bentflange u with which the hooks h are readily engaged by manipulating thehand'le 71?. With the use of a spring roller r, a constant tension isexerted upon the curtain, which serves to keep the hooks engaged withthe flange,and thus connects the hood and curtain, except when thecurtain is intentionally detached. When thus detached the weight of thehood is substantially balanced by the weights 0, so that either thecurtain or hood may be moved independently. Shelves D maybe fixed abovethe range as shown in Fig. 8, and the disconnection of the. curtain fromthe hood affords access to such shelves or to the closets or elevatedovens, when the hood is drawn down,as shown in Fig. 2, as the curtain insuch case may be detached from the hood and lifted by the spring rolleras far as the chains will allow. The chains may be adjusted to fullyexpose the closets or ovens B, as shown in Fig. 2, and when access tothe closets is not required, the curtain may be again drawn down andengaged with the top of the hood, to wholly inclose the passage leadingto the ventilating flue F.

The hood is preferably made of sheet iron The front of the with bar itaround the bottom, and bar to :around the top, to stifien the same, andact outside the top a of the range, to leave a narrow air space Zbetween the two, as shown at the bottom of Fig. 4C. In this figure, thehood is shown in dotted lines in its lowest position, the guides andrear walls I being broken for want of space upon the drawings.

In Figs. 4, 5 and 6, the rear wall I is shown as supplemental to thedetached range, and

formed with the flue aperture F passing through the same, and with allthe fixtures attached to such wall I, for terbalancing the hood.

Wooden plates m are shown attached to the guiding and counwallI, andprovided with sheet iron casings n to form pockets to conceal theweights 0, which are connected by cords o to the frame of the hood. Thepartition upon the inner side of each pocket is formed by a sheet metalstrip "19 secured to the platoon by flange p and bent at its front side.into a channel to embrace the front guide if. the hood, and a handle 72is fixed upon the 1 A groove m which constitutes the rear guide isformed in the plate m, and anti-friction wheels or, x, are attached tothe bars 7t and w of the hood by bolts o projected through the ends ofsuch bars. sides of the wheels 00 run in contact with shoulders 15 whichare formed in the rear The outer guide by the side of the groove m, andupon the front guide by a rib formed upon the wooden strip t. By thisconstruction the hood Q is guided in every direction, while the wheelsare kept entirely from contact with the sheet metal, which I have foundby experience produces a harsh and grating sound. To prevent such sound,I prefer to employ a comparatively non-resonant material like wood forthe guides. Such wood although resonant in many situations, operatescompletely to ,deaden the Vibrations which would be imf parted to thesheet metal by the movement of the wheels. When made of wood, the rearwall and guides may be readily fire-proofed by suitable chemicalsolutions. may also be made of any suitable wovenfabtrio, andfire-proofed by means already well a known, so as to endure the heat towhich it The curtain is exposed without injury.

The weights 0 may be suspended by fireproof cord or by metal band orchain. The

bars 20 and k are. extended backward. from .the sides of the hood intoproximity to the guides, and the ends of the bars are provided withtrolleys 10 carrying the wheels 00, and 1- from whichlugs 20 areprojected toward the I opposite guides and sufficiently near to theirsurfaces to limit backward or forward movement when accidental pressureis applied.

A buffer spring 11 is affixed to the block 6' to contact with the lug 10when the hood is raised, and to thus bring it. to rest without shock, asshown in Fig. 4.

In Figs. 3 and 4 stops 1 are shown applied near the bottom of the hood,and when the hood is drawn down, it is arrested by the contact of thestops with the top of the range or stove. As the entire weight of thehood is supported back of the center of gravity, the pressure is forwardat the upper end of the hood, as indicated by the arrow 0' in Fig. 4,and backward at the lower end of the hood, as indicated by the arrow(1'. The upper wheel 00 therefore runs in contact with the front guideif, while the lower wheel a: presses into the groove m. The cord 0 isattached to the upper trolley and carried over pulley 0 which is fixedina block 6 at the top of the partitionp; the weight rising and fallingin the pocket it upon the outer side of such partition. The springroller r is mounted in brackets Z which are affixed to the front of theguides, and to a board P which closes the top of the pockets n and thespace between the guides. The brakets are tied together at their lowerends by a bolting rod Z, and are curved externally and provided with aflange u to retain a sheet metal casing Z which is extended over the topof the board P into contact with the back piece. If the rear wall of thepassage be of brick work, as in a brick set range, the edge of the sheetmetal Z may be scribed so as to fit the irregularities of the same andthus form a close joint. The casing 97. of the pockets is attached atits front edge to the partition p, and at its rear edge to the margin ofthe wooden plate m, and its back edge may also be scribed to fit brickwork if required. Where the surface is so rough as to require a moreperfectjoint than can be made by scribing sheet metal, I use a packing nof soft material, like felt, which is fire-proofed and fastened to theedge of the sheet metal or between the same and the wall. Bolts 0" areshown for connecting the plates m with the rear wall. Such rear wallmay, as stated above, be made of wood fire-proofed, or of sheet metalsuitably stiffened.

The supplemental wall and guides may be suported upon the range bybrackets a, shown in Figs. 2 and 3, and the tops of the guides steadiedby braces extended to the ceiling or sides of the room.

The aperture of the ventilating fine is usually formed through the rearWall and connected with the ventilating passage 1 between the guides andbelow the top piece P; but in some instances the connection is madethrough such top piece. In some instances the smoke pipe F of the rangemay be we tended upward in front of the rear wall to the ventilatingflue F and extended through the same as shown in Fig. 8, as is sometimesdone where stationary hoods are fixed upon the upper partof the chimneybreast.

The curtain is arranged to move in contact with the front sides of theguides so that the passage 1' inclosed by the guides and curtain formsan extensible connection between the hood and the flue, which ismaintained both when the hood is elevated, and when it is drawn downwardover the top of the range. The curtain is shown in the drawings lappedat its edges over the face of the front guides, and forms ajointtherewith by the indraft of the flue, when the damper in such lineis open. By this construction the curtain is adapted to relax and allowthe heated air to escape into the kitchen when the damper of the line isclosed. The heated air may thus be retained in the kitchen to warm thesame, as in cold weather; while the hood operates the same as in hotweather to intercept the radiant heat from the cook. The room may thusbe kept comfortable and the cook entirely protected from the intenseheat of the range itself.

The hood is shown herein fitted to the entire top of the range, as suchconstruction is the most desirable where the heat is objectionable; butit is obvious that it may, if desired, he confined to a part only of theapparatus; or, as with very wide ranges, such as are used in hotels orships, the hood may be divided into sections, in which case, two or moreseparate hoods would be operated side by side; thus exposing but a partof the range at one time.

It is obvious that springs may be substituted for the weights 0 tobalance the hood, as is common in balancing window sashes. The smokepipe F may, if desired, be conducted through the ventilating flue F, andsuch an arrangement is shown in the detached range in Figs. 2 and 3.

It is common to furnish all such ventilating fines with a damper orregister to close the same at pleasure as shown at R in Fig. 5, and Ihave termed such device a damper in the claims attached hereto. It isobvious that when the stove is not in use for cooking, and is thereforefree from odors, the heated air from the hood may be used for an upperapartment. For such purpose the ventilating fine may be connected withan upper apartment, or a pipe may be taken from the top P. A pipe P isshown extended from the top T, in Fig. 3, to indicate such a connection,and a damper P is shown inserted in such pipe to close the same, whenthe range is used in cooking, and the odors from the range would beoffensive.
